Amazon AMI 的默认yum
存储库似乎不包含 OpenCV 软件包. /p>
您可以通过以下简单步骤从源代码中自己编译它:
sudo yum install git cmake gcc-c++
git clone https://github.com/Itseez/opencv.git
git checkout <required version>
cmake <path to sources>
make
sudo make install
这是基本步骤-之后,您将具有 OpenCV 和一些默认模块.您可以阅读 cmake 输出并在实际构建之前调整安装.可能您应该根据需要安装其他软件包(例如 libpng , libjpg , python 等).
I'm trying to install OpenCV for use with Pastec on an Amazon Linux instance. This is my first time using an Amazon service, and I don't have much experience using linux...
How would I install OpenCV and it's dependencies on Amazon Linux?
I have tried adding the EPEL repository using this command:
$ sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
... which works but it still won't install OpenCV...
$ sudo yum --enablerepo=epel install opencv-core
Loaded plugins: priorities, update-motd, upgrade-helper
948 packages excluded due to repository priority protections
Nothing to do
It seems that default yum
repo for Amazon AMI doesn't contain OpenCV packages.
You can compile it from sources by yourself with the following simple steps:
sudo yum install git cmake gcc-c++
git clone https://github.com/Itseez/opencv.git
git checkout <required version>
cmake <path to sources>
make
sudo make install
It's basic steps - after this you will have OpenCV with some default modules. You can read cmake output and adjust your installation before actual build. Possibly you should install additional packages for your needs (like libpng, libjpg, python etc.).
